Building Code FAQs

Who is responsible for obtaining a building permit?
The property owner is responsible for obtaining the permit. The contractor may get it for the project but if he doesn’t, the property owner is ultimately responsible, not him. Make sure you consult with him before the project begins.

Can a contractor work on a project that would require a building permit without a building permit being issued?
No, the permit must be issued beforehand in order to ensure that the project is going to comply with all Codes. This is also a good time to see if you are eligible for Enterprise Zone benefits.

Do I need a permit to do my roof?
A building permit is required if you put on new sheathing (the plywood under the shingles). The Building Code allows only two layers of shingles.

Only the homeowner or a licensed contractor (registered with the State of Illinois) may work on a roof.

What information is needed on a building permit application before a permit is issued?
